It was the WHO who claimed on 4 jan that person-to-person transmission was impossible. It was CDC and WHO who said asymptomatic transmission was unlikely ("not a driver of the outbreak", "unclear"). It was the WHO who said closing borders and stopping Chinese from entering the country had zero effect on spread. It was the WHO who still claims that packages from China can't cause infection, despite science showing it can survive on plastics for up to 9 days.

China should have all the data on reinfection, and thus, if they share this data with the WHO like they are supposed to, there should be a factual source from the CDC or the WHO. Where is it?

If we stick to the official facts every time a whistle blower opens their mouth, there would be no point in blowing the whistle. Only one who benefits from that are the authorities.

Like the UK government: If China does not share more information, we are forced to assume the absolute worst.
